Forged crankshaft is usually made of superior carbon steel or alloy steel. Heat the steel until it is red. And carry out one step molding by adopting ultra-high pressure. The heat-treating processes of forged crankshaft and cast crankshaft are not quite the same. For internal organization, the forged crankshaft is more stable than the cast crankshaft, because the internal grains are more uniform inside the forged crankshaft. Better internal organization can reduce breaking off of the crankshaft.
